IMPROVEMENT IN LUBRICATING COMPOUNDS- Specification'formin g part ofLetters Patent No. 154,130, dated August 18, 1874 application filed June9, 1874.

' vantages over the lubricating oils and compoundsin ordinary use, bothin cheapness and durability, and which will not turn rancid or decomposeand corrode the iron or othermetal with which it comes in contact, asother lubricating compounds and oils are apt to do.

Our compound also possesses the property of mingling or mixing withsteam, and thus more effectually accomplishing its work when employed tolubricate steam machinery. Our invention is designed particularly to-beused as a lubricant for steam-cylinders and steamchests and the otherworking parts of steamengines, in which the lubricant is liable to comeincontact with the steam.

Our invention consists of a compound of borax, oil, and water. We useeither animal, vegetable, or mineral oil, in the following proportions,viz.: Borax, say, five pounds; West Virginia or other oil, thirtygallons water, say, ten gallons. These ingredients we mix, preferably bythe aid of heat; but under some circumstances they may be combined in acold state, although it takes longer to effect a thorough chemical unionof the difl'erent ingredients when combined without the aid of heat. Weagitate the mass, by stirring or otherwise, after mixing, until the massassumes a homogeneous unetuous form, when it is ready for use. Thecompound we apply in the same manner as the ordinary lubricants, bymeans of the ordinary oil-cups attached to the steam-chests andcylinders of engines, and, as it is liquid, it finds its way to theworking parts of the engine in the same manner as oil.

We do not limit ourselves to the exact proportions of ingredients asabove set forth, because the proportions may be varied without departingfrom the nature of the invention.

Having described our invention, what we claim, and desire to secure byLetters Patent, 1s-

The within-described compound, consisting of borax, oil, and water, inabout the proper tions of five pounds of borax. thirty gallons of oil,and ten gallons of water, substantially as and for the purposedescribed.

In testimony that we claim the foregoing,

we have hereunto set our hands this 1st day I of June, 1874.
